The Forgotten Outpost is a cellar in Kehjistan, and like most cellars it asks you to purge it of enemies. There were only a couple of skeletons and a healing potion pot in the center of the cellar. I killed all of the skeletons, and nothing happened. I still had the objective of purging the cellar of enemies. I tried breaking all of the pots in the cellar, examining the potion pot, and looking all around the cellar, but I didn’t find anything out of the ordinary. Maybe I am missing something, or maybe it’s a bug.
Guess a year on was never fixed as exactly the same issue, as great as game is there are some pretty stupid errors in it.
If I’m not mistaken, you need to actually use the healing pot in the middle of the cellar to trigger the monsters to spawn. There should be spikes around the pot, so you can damage yourself to use the pot and finish the cellar.
